    Abstract: Interstitial brachytherapy is a cancer treatment in which radioactive material is placed directly in the target tissue of the affected site using an afterloader. The accuracy of this placement is monitored in real time using a urinary catheter that locates the radioactive material according to the radiation levels measured by sensors in the walls of the urinary catheter. A scintillator that is embedded in the walls of the urinary catheter produces light when irradiated by the radioactive material. This light is proportional to the level of radiation at each location. The light produced by each scintillator is carried through optical fibers and then converted to an electrical signal that is proportional to the light and the radiation level at each location. The radioactive material is located according to the plurality of electrical signals. This location can be used as quality control feedback to the afterloader.

    Abstract: A plastic scintillating fiber includes: a core containing a transparent resin having scintillating properties and at least one type of fluorescent substance that absorbs the scintillation light and converts the absorbed light into light having a wavelength longer than that of the absorbed light; a cladding layer covering an outer peripheral surface of the core and having a refractive index lower than that of the core; and an outermost peripheral layer covering an outer peripheral surface of the cladding layer and containing a compound of a heavy metal element. The core, the cladding layer, and the outermost peripheral layer are integrally formed.

    Abstract: A subsurface continuous radioisotope environmental monitor that provides a continuous monitoring of the possible presence of radioactive species in subsurface groundwater. The detector and all supporting system elements are specifically constructed and equipped to be permanently mounted in a well or borehole to continuously detect and record radiation decay of radioactive species that are borne by subsurface water flow to that sampling area. The system operates by placing a detection element in a housing such that subsurface water that reaches the bore or well can flow in contact with the detection element. The system can employ several detection modes and materials. The detector includes SiPMs operating in a coincidence spectroscopy configuration to significantly reduce spurious signals due to thermal noise as well as increasing the total amount of signals collected.

    Abstract: A scintillator for imaging using X-rays or gamma rays or charged particles, includes a network of glass capillaries with an inner diameter no greater than 500 micrometers. The capillaries are filled with a polymer material made up of at least (i) a monomer selected from the group comprising vinyltoluene, styrene and vinylxylene and the isomers thereof, (ii) a cross-linking agent made up of a divinylbenzene or a dimethacrylate having a central chain which includes 1 to 12 carbon atoms, and (iii) triphenylbismuth. The cross-linking agent is provided to make up 10 wt % to 60% wt of the mixture thereof with the monomer, and the triphenylbismuth makes up at least 5 wt %. The cross-linking agent is provided in a ratio of 0.75 to 2.25 times the weight content of the triphenylbismuth.
